pH CORRECTION FILTERS
Treat acidic water and increase alkalinity by raising the pH of the water source
WHAT IS pH CORRECTION?
When low levels of pH and alkalinity are in the groundwater, the pH is adjusted by way of the pH correction filter containing either Calcite or Magnesium Oxide.
The low pH level of water is a result of numerous factors, including low alkalinity, chemical composition (especially presence of carbonates, chlorides, sulphates, CO2) and temperature.
Calcite (Calcium carbonate, CaCO3) and Magnesium Oxide (MgO) is a natural substance used to increase the alkalinity of the water and thereby alleviating the corrosive nature thereof.
As the water makes contact with the calcite or magnesium oxide, the media used slowly dissolves and increases the alkalinity and pH level of the water
The low pH water is circulated or passed through the pH correction tank either directly from the bore hole submersible pump or by means of circulation closed loop with a centrifugal surface pump. As the water makes contact with the calcite or magnesium oxide, the media slowly dissolves and increases the alkalinity and pH level of the water.
